Definitions

  • the invention relates to a data carrier arrangement according to the preamble of patent claim 1.
  • the invention also relates to an arrangement of at least two data carrier arrangements and a method for accessing at least one data carrier arrangement of the arrangement.
  • a chip card contains a carrier element in the form of a card with standardized dimensions and at least one semiconductor circuit arranged in a recess or recess in the carrier element.
  • the chip card has a number of connections which lie on the same surface as a main surface of the card within this surface and away from the edge of the card. To contact these connections in a reader, correspondingly complex mechanical devices are necessary. The contact can be made purely mechanically or using electromechanical effects.
  • data carrier arrangements for data processing devices in particular personal computers
  • These data carriers which are standardized, for example, as the PCMCIA standard, contain one or more semiconductor circuits which are accessed by the personal computer.
  • Such a PCMCIA card has a connecting strip on one of its edge sides, which contains pluggable contacts. The connecting lead is inserted into a corresponding connecting counterpart in the personal computer.
  • the conventional data carrier arrangements are only conditionally suitable for storing larger amounts of data. If a processing device is to access several PCMCIA cards, neither a card change is carried out or, if several cards remain inserted at the same time, there must be a corresponding connection socket in the processing device for each card. These connection devices require a relatively large volume. This is in conflict with the desire to constantly downsize electronic devices. In addition, because of their mechanical complexity, plug connections are complex to manufacture and relatively expensive.
  • the object of the invention is to provide a data carrier arrangement of the type mentioned at the outset which is designed in such a way that it can be connected to a processing device at the same time as a large number of other similar data carrier arrangements without complex additional aids.
  • Another object is to provide an arrangement of at least two such data carrier cards.
  • an object is to specify a method for accessing at least one card of the arrangement.
  • connection surfaces of the data carrier arrangement according to the invention are arranged on an edge of the card-shaped carrier element, several cards of this type can be stacked on one another without any problems.
  • the contacts between the connections can then be made via a contact rail in a corresponding connection socket.
  • This socket can, for example, be arranged in an access device. It is also conceivable that the connection socket is handled loosely and the data carrier card in one mechanically 3 solid bond holds.
  • the counterpart can be part of a housing that corresponds in terms of its outer dimensions to the standard dimensions of a standardized device insert (for example a PCMCIA card).
  • connection areas in the area of the edge are also extended to the two main areas of the card, the contacting of several cards placed one above the other takes place without further aids.
  • the size of the connecting surface sections projecting into the two main surfaces of the card are preferably congruent.
  • connection is expediently symmetrical with respect to the center of the edge surface having the connecting surfaces. This means that the data card can be used on the other side without any problems. In addition, there is increased functional reliability, since the functional characteristics of a connection are duplicated.
  • the edge surface of the data carrier card and the card receptacles which have connections have an interlocking surface contour which is in each case opposite one another. It is thereby achieved that the card can only be inserted into the card holder at the edge surface having the connections, forming the electrical contact. If the surface contour is also not symmetrical to a central card axis, it is ensured that the card cannot be inserted with the sides reversed with respect to this axis of symmetry. The electrical contact can only be established if the surface contours of the card holder and the data carrier card mesh with one another and complement each other.
  • the interlocking surface contours can consist, for example, in a bevelled corner of the card and a correspondingly filled corner of the sensor and / or in a recess of the card that is not arranged in the center of the card Recording a corresponding projection of the card holder.
  • the interconnected corresponding connections of several cards lying one above the other act logically as a data bus. Access to the cards is monitored by a control device connected to the connections in the processing device. Each of the cards can be accessed individually or together. In order to be able to address a card in a targeted manner by the processing device, the card contains in one of its semiconductor circuits a non-volatile memory with an identification identifier.
  • the identification mark can, for example, be a sign assigned only for this card. It can be saved as a binary value that corresponds to a number of numbers and other characters. These can e.g. B. include a card number and alphanumeric text. With appropriate coding, for example in the form of one or more check digits, access security can be achieved.
  • the control device in the processing device can query the identification identifier of the card at regular time intervals and thus carry out an identification cycle of all cards.
  • an identification cycle for the bus can be triggered, for example, by closing or opening an electrical contact or by interrupting a light barrier.
  • all other access procedures customary for buses are possible. It is also possible, for example, to transfer data between several cards directly to one another without involving the device-internal control device.
  • a device is preferably provided on each data carrier arrangement, by means of which the circuit parts of the data carrier card can be switched off from the power supply. This will reduce electricity consumption.
  • the device is designed in such a way that a rest phase is recognized, so that one or more semiconductor circuits are then deactivated. The monitoring device remains active for the time being.
  • the identification number assigned to the card When the identification number assigned to the card is received, it is recognized by the device, so that the previously switched-off semiconductor circuits are then supplied with current again. External addressing of the data carrier card is then possible immediately.
  • the monitoring device In a further development of the monitoring device, it is provided that after a certain period of idle state which it monitors, it switches itself off and any other circuit parts of the card which are supplied with current.
  • the monitoring device therefore also has further circuit means with which access to the bus is determined at all. Thereupon these means ensure that at least the monitoring device of the card is switched on again. A received identification identifier can then be evaluated, so that the remaining circuit parts arranged on the card are only switched on again when the correspondence with the identification feature of the respective card is determined.
  • connection piece for further connection to the processing device may well be standardized connections, e.g. B. a PCMCIA card correspond.
  • outer dimensions of the housing correspond to standard-compliant dimensions for ordinary plug-in units, e.g. B. that of a PCMCIA card.
  • positioning means are provided on the data carrier card. These positioning means expediently comprise at least one projection on the main surface of the carrier element, preferably in the edge region thereof.
  • the carrier element On the opposite main surface, the carrier element has a corresponding recess in which the respective projection of another card is received. This ensures a non-slip, exact stacking of the cards.
  • corresponding positioning means can be provided on the edge of the card and on the housing wall opposite it. This can Vor ⁇ cracks or depressions or grooves on an edge of the chip 'map and be depressions or grooves or projections on the opposite housing wall.
  • a segment comprises a plurality of cards, for example 16 or 32 cards arranged directly next to one another, the connections of which are separated from the connections of the cards of a further segment by a buffer device. This achieves load decoupling between the individual segments. Accordingly, only the capacitive load of the connections of this segment acts on the output drivers in a segment. From a logical point of view, all of the segments connected to one another act as a single bus.
  • FIG. 1 shows a perspective top view of the data carrier card
  • Figure 2 is a sectional view in the longitudinal direction of the card.
  • the data carrier card contains a substrate 1, which preferably consists of an electrically insulating plastic material.
  • a multiplicity of integrated semiconductor circuits 10... 18 are arranged on the data carrier card 1.
  • the outer surface of the semiconductor circuits forms a common, essentially flat surface with the main surface of the carrier element.
  • the semiconductor circuits can be introduced into corresponding recesses in the carrier material 1, for example after an encapsulation known per se, in accordance with methods customary for chip cards.
  • the semiconductor circuits are connected to one another via data lines 19. These are only shown schematically in FIG. 1.
  • Connections 20 ... 28 are provided for electrical contacting of the card.
  • the connections are on one edge of the card. They are made of conductive metal.
  • connection region 35 which lies on the edge surface 29, a connection region 30 which lies on the surface of the main surface 31, and a connection region 32 which lies on the surface of the Main surface 31 lies opposite main surface 33.
  • the surface sections 35, 30, 32 are each rectangular and each have a common rectangular edge with the surface 35.
  • Each of the connections 20... 28 is connected to a line 34 and is connected to one or more semiconductor circuits via the lines 19 shown schematically.
  • the connection surfaces 35, 30, 32 of the connections 20 ... 28 can terminate with the same surface area as the surface of the carrier element 1. They can also lie raised on the surface of the carrier element 1, as is shown in the sectional view in FIG. 2.
  • Memory circuits in which data are stored in a non-volatile manner. These data can be, for example, digitized music signals, image signals recorded by an electronic camera, texts (such as entire dictionaries), electronic maps, software for data processing systems, etc.
  • the semiconductor memories can be writable and erasable memories or only read-only memories (ROM).
  • the data are preferably stored in compressed form with regard to their redundancy.
  • the semiconductor circuit 18 performs control functions. If the data is stored in compressed form, the circuit 18 carries out the decompression when reading out and, if appropriate, the compression when reading in.
  • the control device 18 is expediently a microprocessor. It also contains the memory for the identification mark. In addition, the control device 18 contains the monitoring device for the current management. This device ensures that after a predetermined period of rest the memory circuits
  • the card has semicircular projections 40, 41, 42 on the longitudinal edge of a main surface of the carrier element 1. Opposite the projections 40, 41, 42, depressions 43, 44, 45 are made in the main surface 33, into which the projections of another data carrier card can engage. This makes it possible to position the additional card under the carrier card 1 in a non-slip and correct position, so that electrical contact is made with the connections of the further cards on the contact surface 32 of the connections 20 ... 28 in a simple manner.
  • the card has projections 52, 53 on the edge surfaces 50, 51. If the data carrier card is inserted into a housing provided for this purpose, the projections 52, 53 can engage in corresponding grooves there, so that the data carrier card is held securely in the housing.
